CJSMF36CA from Changjing, in a SOD-123FL. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A1 | passive | Bi-directional TVS terminal with no cathode band on the CA part, 36V VRWM, 40.16-44.17V breakdown at 1mA, 57.5V max clamping at 3.5A. |
| 2 | A2 | passive | Second bi-directional TVS terminal, interchangeable with the other since the CA part has no polarity marking (cathode band is for uni-directional parts only). |
